Frame Delay
Set the number of lines delayed between the input signal and its appearance on screen, keeping in mind that
projector processing always adds 1 frame of delay to the frame delay setting. For applications such as
simulation, where the feeling of "real time" image response is a priority, a minimum setting is usually
preferable. For projectors capable of 3D (stereographic) applications where alternating left-right frames must
be synchronized with the corresponding L/R shutters in 3D glasses, a total frame delay setting of two (or
multiple of two) may be more useful. If set too high or low, frame locking will not be possible-most sources
require approximately 50 lines of delay to ensure frame locking.
Dark Interval
Adjust Dark Interval to artificially increase the amount of dark time between displayed frames for
stereographic 3D images. Higher settings provide more time for shutters in 3D glasses to open/close, ensuring
that each eye sees the full display intended for it. Symptoms of cross talk and/or color artifacts can indicate
need for adjustment. The Dark Interval range of adjustment depends on the vertical frequency of your source-
the higher the frequency, the smaller the range.
NOTE: For more information, refer to separate the Using 3D in Mirage manual provided.
3D Stereo Sync Locking
This option defines 1) whether or not the incoming stereographic 3D signal locks to the vertical sync output so
that signals are synchronized, and 2) whether or not the 3D frames must be inverted, i.e. swapped left-with-
right. The correct setting ensures that the projector's 3D display of left/right frames is synchronized with the
rest of the 3D system components so that the intended eye sees the left/right image data. Select the option
corresponding to your 3D source connections and timing, and use only if the Mirage 3D Stereo Sync cable is
connected between the projector's GPIO port and a server. Keep this adjustment OFF (default) when you are
not using the Mirage 3D Stereo Sync cable.
With your sync cable and, if desired, emitter connected as described in the Using 3D in Mirage manual, select
the option suited to your 3D configuration (see above). If Frame Delay is 2 (or 0), do not invert; if frame delay
is 1 or 3, invert. Generally, an "Unlocked" setting is synchronized with the incoming L/R signal rather than the
vertical sync output, and may be needed only with multi-projector installations in which the vertical sync
outputs vary.
NOTE: For more information, refer to separate the Using 3D in Mirage manual provided.
3D Sync Input
Define which of the Mirage 3D Stereo Sync Cable's input connecters is routed from your server. Use only if
the cable is present. Only the first projector, possibly connected to external sync, will choose any of these
selections. Every other projector will be getting sync from the previous projector on
